Inflatable object with pressure sensitive pump

ABSTRACT

An inflatable object with a sag to enclose pressurized air to a predetermined threshold pressure and to obtain a shape, a decorative dress to cover at least a portion of the sag and having characteristics of an object having the shape when covering the sag outer surface, couplings on the sag outer surface to which the decorative dress is attached, a frame to support at least a portion of the sag, an electric air pump coupled to the sag by a unidirectional inlet valve, and to provide the insufflated air to the sag, a sensor coupled to the sag and configured to detect sag air pressure; and a controller, coupled between the sensor and the pump. The controller operates the pump to automatically maintain a threshold pressure of air within the sag as sensed by the sensor. The sensor and the controller are disposed on the sag surface.

BACKGROUND 1. Field of the Invention

The present invention is related to inflatable objects and, in particular, to inflatable objects with pressure sensors.

2. Background Art

Typically, inflatable objects are limited in shapes, such as tubes and beach balls, and can be difficult to store and to ship. Also, some inflatable objects, such as furniture (e.g., a chair), are uncomfortable to sit in and may deflate slowly during use. In addition, inflatable objects can be cumbersome to inflate. An inflatable display is mostly a plastic body sewn with outer layer decorations. For this type of display, it cannot be folded, often needs to disassemble the finished goods to ship, and therefore, needs much larger room/space to ship and store, increasing the shipping costs.

Moreover, inflatable objects often do not have the cosmetic appeal as stuffed or carved display figures do. A large plush animal or display object may be expensive, and difficult to produce, ship, and store. Typical inflatable furniture and bean bags are not equipped with a sensor to control the air pressure within the forms. Further, it requires a longer time and more labor to assemble, therefore, a product that is easily folded, easily assembled and keeps its the shape is needed.

It should be noted that the features illustrated in the drawings are not necessarily drawn to scale, and features of one embodiment may be employed with other embodiments as the skilled artisan would recognize, even if not explicitly stated.

DESCRIPTION OF THE EMBODIMENTS

The embodiments herein can provide for plush objects of large size, large life-like displays, and whimsical presentations with ease of production, storage, and shipping, and with far less expense. It is possible to have the realistic cosmetic look as a plush or stuffed objects with the size of regular inflatable products. FIG. 1 represents a partially dressed SAG 110 having at least one prop 190. FIG. 2 represents one leg with frame 195 of FIG. 1. FIG. 3 represents object 100 with dress 150 of a snowman. FIG. 4 is a block illustration of pump 120, dual inlet valves 140, 145, sensor 160, and pump controller 170.

FIGS. 1-4 are emblematic of embodiments herein that provide a new inflatable object 100, which includes a highly flexible container, or SAG 110, which can enclose an insufflation gas; pump 120 providing the insufflation gas to inflate SAG 110; and dress 150, which can flexibly cover the SAG 110 as it is either inflated or deflated. SAG 110 can be a lightweight, tough elastic material, such as polyvinyl chloride (PVC), a thermoplastic elastomer, including thermoplastic rubber (TPR), polyethylene (PE), and other like materials. Insufflation gas can be, for example, air, nitrogen, helium, or other commonly-available gas. SAG 110 can have at least one valve 130 by which to deflate SAG 110, and one valve 140 by which to inflate SAG 110. Valve 130 can have an inlet on the interior of SAG 110, and an outlet on the outer surface of SAG 110. Valve 130 may be configured to rapidly deflate SAG 110. Valve 140 can be used to inflate SAG 110. Valve 140 can be positioned at or near SAG 110 bottom. Valve 140 can be a unidirectional valve, configured to allow gas flow into SAG 110.

Coupled to valve 140 inlet can be pump 120, which pumps gas into SAG 110. A second inlet valve 145 may be coupled to pump 120 outlet to further ensure that no gas escapes during insufflation of SAG 110. Dual inlet valves can further ensure that there is no leak on the SAG inflation input side. Pump 120 can be an electric pump. Coupled to operate pump 120 can be sensor 160 attached to controller 170. Sensor 160 detects the current inflated state of SAG 110 and, if the inflated state is below a predetermined threshold, controller 170 causes pump 120 to insufflate gas into SAG 110. By using pump 120, SAG 110 can be inflated more quickly than by manual methods. Pump 120, therefore, maintains SAG 110 at a predetermined inflation state. SAG 110 can be configured to be a wide variety of shapes, including practical, holiday, or whimsical shapes. Dress 150 can be configured to conform to an inflated SAG 110 by enrobing SAG 110 with dress 150, prior to inflation. Dress 150 can include, without limitation, Characters, Animals, Symbols, Vegetables, Fruits, Bean bags, Clothing, Furniture, or Objects. Alternately, dress 150 can be disposed on SAG 110 after inflation has been achieved. Dress 150 can be a thin covering that gives SAG 110 an appearance and texture consistent with its shape—for example, a chair, a table, Santa Claus having a red-and-white felt-like costume and shiny boots, or a large, stuffed moose.

A dressed object 100 can be inflated and maintained in appearance for the duration of its presentation by operation of sensor 160, controller 170, and pump 120, in concert with valve 140 and, if present, valve 145. Dress 150 can be attached to SAG 110 by couplings 185, which may include connecting rings or hook-and-loop attachments. Dress 150 can be a tactilely-pleasing material, including nap, velvet, or plush. Props 190 also can be attached to dress 150 to further accentuate the appearance of object 100. A prop 190 can include without limitation, a hat, shoes, a sword, a cap, a fishing pole, a scarf, or socks. Frame 195 may support at least a portion of SAG 110, if it is used at all. If used, frame 195 may support SAG 110 but be concealed by dress 150.

In general, once pump 120 is activated, sensor 160 senses a deflated state of SAG 110, and controller 170 causes pump 120 to insufflate gas into SAG 110, up to a predetermined threshold pressure within SAG 110. If gas leaks out of SAG 110 and SAG 110 pressure falls below the predetermined threshold pressure, controller 170 will cause pump 120 to insufflate gas into SAG 110 up to the predetermined threshold. In this way, the overall shape, size, and cosmetic appearance of SAG 110 can be maintained. However, if a large hole erupts and pump 120 operates longer than a preset period, for example, without limitation, 20 minutes, pump 120 will automatically shut off to prevent pump 120 overheating. Pump 120 may be driven by AC or by DC power.

Once the period of presentation is over, dress 150 can be removed from SAG 110, and SAG 110 can be deflated. In the current embodiments, both SAG 110 and dress 150 are thin, sturdy, and easy to store and to handle. Frame 195 can be broken down into a manageable size and configuration to allow for easy storage. In some embodiments, controller 170 is integrated with sensor 160, and may be disposed on the surface of SAG 110. In other embodiments, controller 170 can be separate from sensor 160. It may be attached to pump 120. In embodiments, pump 120 may be contained within support frame 195. This configuration can provide concealment and protection to pump 120 without affecting overall appearance.
